Hey Kenney, just bought AssetForge DeluxeI was on the fence until the sale, and it's amazing :)
I can think of two major upgrades that I'd like: One would be to make AssetForge browser based, like Construct 3. Being able to use software on a Chromebook (the school I teach at uses Chromebooks and Chromeboxes exclusively) would help bring your software to the educational space, I for one would personally advocate for this.
I've been developing a game using Construct 3's browser-based system and being able to use it anywhere, either on my chromebook or on my phone without having to install it is just too good.
All this being said, I probably wouldn't use AssetForge on my phone, for anything other than texturing, but the portability of browser based would give me the option eitherway. I've never connected a mouse and keyboard to my phone :)
2nd upgrade would be the ability to animate models but hey, perhaps there is piece of software similar to yours that caters for animation. I'll have a look.
Congratulations on Asset Forge and I look forward to using it in my games and other artworks :)
